Occupying only two rack units, the PTX1000 is the industry’s first fixed-configuration core router that enables service providers to organically distribute peering points throughout the network. It uses a rich IP/MPLS feature set without sacrificing performance or deployability, two factors on which total cost of ownership (TCO) pivots for service providers.

Like other routers in the PTX Series, the PTX1000 is powered by Juniper Networks ExpressPlus™ custom silicon to deliver predictable IP/MPLS packet performance and functionality.

Increased interactions between people and machines are creating huge volumes of traffic with increasingly unpredictable patterns. These dynamics have intensified the challenge of accommodating growth with traditional network products and architectures. A new approach, based on both physical and virtual innovation, will help service providers stay ahead of growing traffic demands while remaining profitable. PTX Series Packet Transport Routers with custom ExpressPlus silicon, built from the ground up with SDN in mind, deliver an architecture that reduces TCO with highly flexible, high-performance innovations that are easy to deploy.

Product Description

Juniper Networks® PTX Series Packet Transport Routers transform the core network with physical and virtual innovations that deliver unprecedented scale at a low cost. Two fixedconfiguration platforms are available: the PTX1000 Packet Transport Router, the industry’s first 2 U packet transport routing device; and the PTX10002 Packet Transport Router, a second-generation device that doubles the density of the PTX1000 with Juniper Networks ExpressPlus™ silicon. These packet transport routers give cloud and communication providers the freedom to develop and deliver new virtualized services anywhere in the network. They can also create an elastic architecture with precise traffic control without compromising the service experience.

The Evolving Landscape

New traffic dynamics such as mobility, video, and cloud-based services are transforming traditional network patterns and topologies. Stratified, statically designed, and manually operated networks must evolve to support the constantly growing volumes of traffic quickly and economically. Many operators have seen their profits stagnate and TCO grow under the burden that these growing traffic volumes are imposing. Service providers need to become more agile in order to optimize their existing network resources, shorten planning cycles, and remove rigid network layers.

Operators are facing the following challenges under the current environment:

Static scale: The cloud and communication providers’ backbone handles the full weight of network traffic. Therefore, it is paramount that the core network be able to grow organically along with traffic to meet escalating demands. Silicon, system, and SDN innovations for the core empower service providers to scale faster than the traffic in an elegant, elastic, redundant package—without requiring forklift upgrades.

Static architecture: Virtualized services and the explosion of cloud-based applications are creating increasingly unpredictable traffic patterns. To handle this unpredictability, service providers need a dynamic, scale-out architecture across all layers to create programmable, traffic-optimized networks that support any service, anywhere.

Power costs: For cloud and communication providers, the operational cost of transmitting a packet through the core is less than the cost of the power required to move that packet. In fact, projections suggest that over a few short years, the total power draw will exceed the cost of deploying the entire network infrastructure. Efficient power utilization by the core router requires a holistic ground-up engineering approach.

Physical innovations at the core silicon level enable the PTX Series fixed-configuration routers to lower OpEx. Powered by ExpressPlus silicon, these devices build upon the Juniper Networks Junos® Express silicon concepts of low consistent latency and wire-rate packet performance for both IP traffic and MPLS transport, without sacrificing the optimized system power profile. These concepts are incorporated into the PTX Series design along with full IP functionality, preserving the spirit of the original Junos Express chipset. The ExpressPlus silicon is the first purpose-built telecommunications silicon to engineer a 3D memory architecture into the base design for more than 1.6 billion filter operations per second, dynamic table memory allocation for mammoth IP routing scale, and enormous power efficiency gains.

While the ability to meet service provider needs for performance, deployability, and SDN control begins with the silicon, the integration of optical transport with 100GbE-coherent technology further improves the economics of the core network. With PTX Series Packet Transport Routers powered by ExpressPlus silicon, service providers can now deploy an architecture with the efficiency of a lean-core network featuring Juniper Networks NorthStar Controller, a robust, full-featured Internet backbone router. The ExpressPlus silicon also allows service providers to deploy a converged regional IP/MPLS core router with integrated 100GbE coherent transport for superior performance, elegant deployment, and SDN programmability.

PTX1000

The PTX1000, with its rich IP/MPLS feature set, lets service providers organically distribute peering points throughout the network without sacrificing performance and deployability—the main contributors to eroding TCO for service providers when peering. The PTX1000 expands the applications scope that the PTX Series architecture addresses, enabling service providers to implement a distributed core architecture for interconnecting growing cloud services. Service providers can distribute peering points to match traffic demand with an optimized core router without sacrificing performance or deployability. The PTX1000 is a first-generation fixed-configuration core router in a compact, 2 U form factor, making it easily deployable in space-constrained Internet exchange locations, remote central offices, and embedded peering points anywhere in the network, including cloud-hosted services.

PTX10002

The PTX10002 is a second-generation PTX Series fixedconfiguration core router, featuring a compact, 2 U form factor that is easy to deploy in space-constrained Internet exchange locations, remote central offices, and embedded peering points throughout the network, including cloud-hosted services.

ExpressPlus Silicon

Like the rest of the PTX Series, the PTX1000 and PTX10002 are powered by ExpressPlus silicon, delivering predictable IP/ MPLS packet performance and functionality. ExpressPlus silicon also eliminates the complex sawtooth packet profile found in elaborate over-engineered network processing units (NPUs) deployed in other core routers. This delivers the distributed peering scale (more than 2 million forwarding information base [FIB] and 5 million routing information base [RIB], also known as forwarding and routing tables, respectively), required to match expanding traffic demands.

Features and Benefits:

Performance is one of the guiding design principles for the PTX Series Packet Transport Routers. This focus empowers service providers with superior scale to match increased traffic levels and network engineering challenges with predictable system latency to improve the overall service experience, deliver best-in-class resiliency, and ensure that services meet strict customer servicelevel agreements (SLAs).

Deployability is the other guiding design principle for the PTX Series routers, focusing on power, space, and weight—fundamental concerns that impact service providers’ operational budget with respect to growing traffic.

SDN programmability brings virtual innovations to the service provider core, while the NorthStar Controller is an open, standards-based solution that optimizes both the IP layer and the transport layer with precise SDN control, allowing service providers to automate and scale operations.
